GAS-STOVE.

.Application led November 18, 1896. Serial No. 612.557. (No model.)

.T all whom it nto/y concern.'

Be it known that I, PATRICK J. C Assnnv, a citizen of the UnitedStates,residing at Columbus, in the county of Franklin and State ofOhio, have invented a certain new and useful Improvement in Gas-Stoves,of which the 'following is a specification.

My invention relates to the improvement of gas-stoves; and the objectsof my invenro tion are to provide astove of this class adapted for theuse of natural Vor artiiicial gases; to so construct and arrange theparts of my improved stove as to provide an increased radiation of heatwithout a corresponding increase in the volume of gas consumed; to soconstruct my improved stove as to provide for perfect combustion and toprovide certain improvements in the construction and arrangement of theburner-plate, whereby an zo increased heating and radiation surface isproduced, and to produce other improvements the details of constructionof which will be more fully pointed out hereinafter. 4These objects Iaccomplish in the manner 2 5 illustrated in the accompanying drawings,in which- Figure lis a front elevation of my improved stove Fig. 2 is aside elevation of the same. Fig. 3 is a vertical section of said stove,and 3o Fig. 4 is a detail view in perspective of a portion of one of theburner-plate radiatingstrips.

Similar letters refer to similar parts through'- out the several views.

In the construction of my improved stove I provide a casing a, of sheetmetal or other suitable material, said easing being provided with anopen front which is provided with a suitable frame b. 4o vide aburner-plate c, which, as shown in the drawings, is inclined from apoint in the upper and forward portion of said casing to a point in therear and lower portion thereof. This burner-plate c is provided with afor- .45 ward projection c in its upper portion. The projection entendsnearly to the front of the casing and forms an additional obstruction tothe passage of the hot air and thereby causes more heat to be radiatedinto the 5o room. It also forms a hollow chamber within which theconfined air is heated more quickly and escapes into the room.

Within ythe casing a l pro-' As indicated in the drawings, the upperportion of the casing above the burner-plate is provided with ahorizontal liuc d, the latter communicating in its rear portion with avertical ue e, which is adjacent to the back of the easing d. Betweenthe iiue @,'inclined burner-plate c, and flue d is formed an airchamberf, which through the medium of the desired number of short verticaltubes f communicates with the interior of a top chamber g, which may beformed above the iiue d.

In case of the employment of the top chamber g I may form in the upperand transverse portion of the frame b suitably-arran ged perforations oroutlets g.

At a suitable point below the iiue d the back iiue e is provided with anoutlet e2, which may be made to communicate with a suitable pipe.

h represents separated transverse radiator and dame deiiecting strips,which, as indicated .in the drawings, are secured by rivets or otherwiseone above the other to the outer face of the burner-plate. Each of thesestrips has formed therewith at desirable intervals outwardly extendingand downwardly -inclined projections e', the latter preferablyterminating in rolls, as indicated more clearly in Fig. e of thedrawings. This construction and arrangement of the projections forminverted-V-shaped spaces between each projection and the plate, withinwhich the ascending current of heated air is kept until it can force itsway to the ends of the projections, which will retard its upward passageto a greater extent than if the attachments of the projections to theplate were smaller and did not extend in a horizontal direction acrossthe plate. By inclining the plate forward it is evident that any airthat might escape at the edge of these projections would ascend in astraight line and be caught in the projections above it, and thereby thepassage of the air would be retarded and a larger amount of heat wouldbe radiated into the room.

Through the sides of the casin g @are formed suitable openings awhich,as indicated, cono- Inunicate with the interior of the airchamber f.

In front of the lower end portion of the burner-plate c is supported adesirable form of gas-burner m, to which leads a suitable IOO
